What is your largest unit?

a 20lt, but this is not suitable for home use other than to heat a Jacuzzi as its minimum flow is 10lt/min which is faster than a basin tap will cope with. This means that it will shut off if the required flow is not there. It also takes 2 x 48kg cylinders and a 4kg regulator to operate it.

Will a larger unit use more gas?

It will use the gas quicker but will produce more hot water. A liter of water require a certain amount of gas to heat it regardless of the size of the unit.

Can I use one geyser for the whole house?

Yes providing only one tap is used at a time. Ideally you should have one unit to run the bathrooms and an 8lt for the kitchen. This because in the bathroom you would set the unit to supply water at 40 degrees and in the kitchen 55 degrees. Our new 16lt constant temperature unit does allows you to now run two taps at the same time.

How do I set my geyser temperature?

The temperature coming out should be the temperature you will use it at. It does not make economic sense to spend money heating water and the adding cold to cool it to the right temperature. Set the gas on maximum and the temperature on minimum. If it’s too hot decrease the gas flow. If it’s too cold the increase the temperature setting. Your temperature setting is actually a water flow rate setting. The hotter you set it the slower the rate of flow. At the hot setting the water flow will be half the flow the unit is rated at i.e. a 12lt unit will flow from 12lt/min to 6lt/min. The new constant temperature unit allows you to digitally set the temperature you want

My Geyser is not working?

The most common fault is flat batteries. Use Duracell Plus and change the every 9 months. When batteries become flat they can still fire the igniters and work the unit for short periods, the same as a torch with flat batteries will have a bright light that then dims. If you change the batteries and it still does not work then call us when you are at the unit and we can go through some basic diagnostics.

What do I do in freezing conditions?

When you are expecting freezing conditions turn off the stop cock on the cold water in pipe. Undo the knurled stem that hangs down on the bottom right hand side of the unit. This drains the unit and stops the water from freezing to ice and tearing the diaphragm or even breaking the manifold.

Can I mount these units outside?

Yes providing they are out of the rain away from sprinklers and strong wind. If you mount it inside then you will need a flue to duct the burnt gas to the outside. If they are exposed to the elements then get a protective cover

Can I mount them in the roof?

No you must have access and a visual contact so that if there is a gas leak which catches fire it is seen immediately.

Can I use this with my solar geyser?

Yes you can, however the two systems need to be isolated from each other so that once your solar water is too cool you can switch over to the gas geyser which has its own cold water supply.

Can I use one geyser?

Yes but it is not ideal if you have many baths, showers and basins. Please have a look at the chart, “choosing the correct geyser” to familiarise yourself.
